FLASH LIGHT.

Application filed December 21, 1921. Serial No. 523,842.

To all whom it may concern: 1

Be it known that I, EDMUND R. BARANY, a citizen of the United States,and resident of the borough of Brooklyn, county of Kings, city and Stateof New York, have invented certain mnewfland useful Improvements inFlash Lights, of which the followin is a specification.

y invention relates to flashlights and has for one of its objects theprovision of such a device so constructed that the particular form ofelectric connectors employed therein may be utilized to center andretain the reflector together with its various cooperative elements inproper relative positions with respect to the battery container andreflector head during assembling and thereafter retain the assembledelements correctly positioned. so A further object of the invention isto so construct the various cooperative elements enterin into thecombination as to produce a flashlight which is strong, durable, easilyassembled, and reliable in operation. at To these and other ends myinvention consists in certain improvements and combinations of parts aswill be pointed out with greater particularity in the clalms appended tothis specification.

In the drawings Figure 1 is a longitudinal section showing my inventionembodied in a flashlight.

Figure 2 is a top plan view of the device shown in Figure 1, with thereflector re 5 moved. V

Figure 3 is an enlarged perspective of one of my improved connectormembers. I

Referring to the drawin wherein my invention is shown embodie inaflashlight.

the numeral 10 indicates a housing or casing preferably constructed fromfibrous or other insulating material within which a battery 11 or othersource of current is arranged. The casing or container 10 carries at oneend thereof a reflector head 12 the outer end of which is screw-threadedto receive a lens ring 13 adapted to retain in position the usual formof lens 14 which is mounted directly upon a reflector 15, the reflectorat its outer end being spaced an appreciable distance from the outer endof the reflector head 12 as shown in Figure 1 to preventshort-circuiting as will e readily appreciated. The reflector 15 is ofthe parabolical type Jcorrectly located, and to prevent any tion thereofwith respect to the container 10.

and is provided with angularly disposed extensions or tubularprotrusions 16 which are screw-threaded as shown, and are adapted toreceive and retain in an angularly disposed relatlon, a plurality of:electric lamps 17 provided with the conventional formof screw threadedouter contacts 18 which are maintained in screw threaded engagement withthe screw threaded portions of the protrusions, 16.

One side of the current supply is electrically connected with thereflector 15 by a more or less resilient contact strip 19 wherei as theother side of the current supply is adapted to be connected with thereflector 15 through the outer contacts, 18, the lamp filaments, notshown, and the central contacts 20 of the lamps by means of suitableelectrical connectors 21, 22 and 23 which are supported by the casing 10and through which the current may be controlled byany suitable form ofswitch not shown.

The connectors 22 and 23 function also as supports for the reflector 15and are of a peculiar shape as clearly shown in Figure 1 they being soformed as to enable the reflector 15 to be easily inserted or removedfrom the reflector head 12 as the occasion may require, to insureaccuracy in placing the same in position, to positively retain the samerota- The connectors 22 and 23 are bent to acute angles as shown mostclearly in Figure 3 and terminate at their outer ends in'con'tact bases24 provided with upwardly and slightly outwardly projecting side orlooking members 25 and 26. These members 26 -are'at their upper endsflared or curved outwardly to a greater extent than are the ends of theside members 25, this being done for the reason that such aconstructionmakes possible a more easy removal or insertion of the reflector 15 aswill be readily appreciated inasmuch as it becomes necessary to springthe connectors 22 and 23 and particularly the side members 26 thereofoutwardly or awa from. each other when the reflector 15 1s eitherinserted or removed.

To prevent short-circuiting of the current between thereflector 15 andthe connectors 22 and 23 when the reflector 15 is positioned as shown inFigure 1, I provide insulating sleeves 27 which are threaded upon' thescrew threaded protrusions 16 and are adapted to snugly fit between theside members 25 and 26 of the connectors 22 and 23. From Figure 1 itwill be seen that the insulating sleeves 27 rest upon the connectors .22and 23 in a position approximately or substantially directly over theend of the casing 10,.fso that part of the weight of the lamps and thereflector is carried by the connectorsfat a point where the bendingmoment is practically zero, by which arrangement any tendency-of themore or less resilient connectors to be" bent out of shape by the weightof the reflector and lamps is practically eliminated. However, a certainamount of thrust is exerted upon the connectors 22 and 23, and also uponthe conductor 17 by the lamps 12 inasmuch as the central contacts 20 ofthelamps engageand slightly move these members under tension when thereflector 15 is placed in position, the inherent resiliency of thesemembers being taken advantage of to maintain the central contacts 20 ofthelampsin intimate f electrical engagement. with the conductor 17 andthe connectors 22 and 23.
